Array initialization-CodePudding

Array initialization error, int a [10]={0} so may not assign any initialization

CodePudding user response:

Int a [10]={0}; Such initialization is possible, but only a [0] is initialized to zero, the main problem is that your code int a [k], array declaration, length should be a constant, should not be you calculated the runtime variables,

CodePudding user response:

A is not sure about the size of an array, the size is determined by n, C language does not support an array variable, the original poster can use dynamic application space form the application space (as an array)

 a=(int *) malloc (sizeof (int) * k); 
if (! A) 
The exit (0); 
Memset (a, 0, k * sizeof (int));
